To alli/whom t may concernf tained, the ink always being worked in one.

direction and the form rollers `always being in contact with thevibrators during both the printing and return strokes of the bed forinsuring a thorough distribution of the ink on the 'form rollers, meansbeing provided for raising and lowering the inking mechanism bodilywithout interfering`- Y with the connection between the several parts.In the accompanying drawings, Figure 1 represents 1n side elevation somuch of a bed and cylinder printing press as will give' a clearunderstanding of the invention. Fig. 42 is a detail view showingthemeans for vibrating the ink cylinder and vibrator rolls, Fig. 3 is adetail longitudinal vertical section through the inking mechanism andits raising and lowering means, Fig. 4 is a detail transverse verticalsection showing the'mean's for raising and lowering the ink` lingmechanism, and Fig. 5 is a detail section showing certain of the gearedconnections.

` `The sheet delivery mechanism and the mechanism for reciprocating theform bed are not shown herein as they form no part of the presentinvention and will not assist in a clear understanding thereof.

The reciprocatimg bed is denoted by 1 and the` form thereon by 2;theimpression cylinder l"by 3, the fountain roller by 4, the ductorroller by 5, the ink cylinder by 6,- the distributing and carryingrollers by 7, 8, 9, 10, 11, 12; the vibrators by 13',` 14, and the formrollers by 15, 16, 17, 18.

The main drive shaft is indicated-at. 19, which shaft drives the camshaftl26. through the gears 20, 21, 22, 23, 24, 25. The cams forcontrolling the movements ofthe foun-A tain roller 4 and theductorroller-,51,2are'dejjj noted by 27, 28 respectively, and theirshaft Vby 29, which shaft is driven from the cam shaft 26 through thetrain of gears 25,- 30, 31, 32, es, 34.

, The impressioncylinder 3 is driven from the drive shaft 19, throughthe gears 20, 21,v 35, 36. The' ink cylinder 6 is driven from theimpression cylinder gear 36, through the gears 38, 39, 40, 41, and thevibrators 13, 14, are driven from the ink cylinder gear 41, through thegears 42, 43' and 44, 45

, respectively.

The vibrator rolls 13, 14, and the ink cylinder '.6 may be vibrated byany desired means, such, for instance, as that shown in the accompanyingdrawings, in which the shaft 6* of the ink cylinder 6 is reciprocatedlongitudinally by the worm 46 and worm wheel 47. The shafts 13* and 14*of the vibrator rolls 13, 14, are reciprocated longitudinally by therock levers 48, 49,

from the ink cylinder shaft 6*.

l'llhe di'erent parts of the inking mechanism are supported in asupplemental frame 50 hinged at 51 to the main frame to swing verticallyto move the form rollers 15, 16, 17 18, into and out of engagement withthe form 2. The means which 1 employ for raising the frame during thereturn stroke of the bed comprises a cam 52`lixed to the shaft 26, whichcam engages aroller 53 on an arm 54 of a rock lever pivoted at 55, `saidlever having' preferablytwo arms 56 connected to the free .end of thesupplemental frame 50, by vertically arranged rods 57. This cam 52 onthe shaft 26 is so timed that the supplemental frame 50 will be loweredto bring its form rollers into contact with the form 2v during theforward printing stroke of the bed and, will be raised tocause the'formrollers to Aclear the form during the return stroke of the bed.

It will be seen by the above construction I nee plishing the resultsherein stated; hence I do not wish to limit myself to the constructionherein set forth, but

What I claim is:

1. In a machine of the character described, a main frame, asupplementalframe hinged thereto, a reciprocating bed and its formcarried bythe main frame, an inking mech' anism for the form carried bythe supplemental frame, and rotary means having an uninterrupteddriving` connection with the inking mechanism arranged to automaticallyraise and 'lower the supplemental frame for bringing the inkingmechanism out of and into contact with the form.

2. In a machine of the character described, a main frame, a supplementalframe hinged thereto, a reciprocating bed and its form carried by themain frame, an inking mech'- anism carried by the supplemental frameincluding an ink cylinder, a pair of` vibrators driven continuously inone direction therefrom and a pair of form rollers driven continuouslyby each vibrator and rotary means having an uninterrupted drivingconnection with thel inking mechanism arranged to automatically raiseand lower the supplemental frame for bringing the form rollers out ofand into contact with the form.

3. In a machine of the character described,

a main frame, a supplemental frame hinged thereto, a reciprocating bedand its form carried by themain frame, an inking mechanism carried bythe supplemental frame including an ink fountain, its roller, a ductorroller, an in-k cylinder, distributing rollers, carrying rollers,vibrators, and form HOWARD M.
